Extending forwardly from the front wall 5 below the tray 31 is a bracket32and de- 'ftachably' supported upon this bracket is a coiee receptacle33, said receptacle being disposed below theuchute 29 so as to receivethe coffeeA therefrom. The'rear wall of this receptacle'is formed withan opening 34 and this opening is covered by a screen 35. Extendingrearwardly from the receptacle and around saidopening is a nipple 36whichv fits within a nipple 37 formed on the front end of a rearwardlyextending air conduit 38. v

The rear wall 6 of the casing A, which mayif desired be formed in twoparts, as indicated at 39 and 40, has its lower portion shaped to formone side of a fan casing, as indicated at 41. The other side, 42, ofsaid casing is detachably connected to the lower f to ysection 40 ofsaid rear wall.

Detachably mounted upon the side 42-of said fan casing is a bracket 43which supports a motor 44 'of any suitable type, such, for instance, as'

an electric motor. yThis motor includes an armature or drive shaft 45which extends forwardly into the fan casing B through a suitable openingformed in the side 42 of said casing.

Fixed onl the shaft 45 is a suitable fan which, in the present instance,is a suction fan 46, and is arranged within the fan casing, the' latterbeing provided concentrically with the fan with an air inlet Opeliing,as shown at 47, and also with an outlet opening 79. Means areprovidedfor ,con necting this fan with any one of the plurality of devices inwhich the coffee is subjected to treatment. The roaster'is here shown asembodying two of these devices, one the container 16 and the other thecoolreceotacle Other devices, such, for example, as a stoner or cleaningdevice, are frequently employed. with the collec roaster andare mountedadjacent thereto but inasmuch as such a. device is of a well knownconstruction l have not illustrated the device itself but have merelyshown means for connecting the fan with such a device. To connect thesedevices with the fan a series of conduits are provided leading from therespective devices to the inlet opening or .conduit 47 of the fancasing. One of these conduits, which is indicated at 57, forms anlextension of the conduit 23 which is con'- nected with the coffeecontainer-'16, and this extension is formed by the back wall 4() and anextension 49 of the partition or wall 23. The lower part of the conduitis partially closed, sutlicient space being left between the end 54 ofthepartition 53 and the end 50 of the wall 49 to form a port leadingfrom the conduit 57 to a vValve chamber 51 in which is mounted arotatable valve member C. The conduit 3B leading from the coolingreceptacle 33 hhs an extension or continuation, as indicated at 56,which also communicates with the valve chamber 5l, and, in the presentinstance, this extension 56 is formed be,- tween the wall 49 and thepartition or, wall 48the lower portion of which is shaped to form one ofthewalls of the valve chamber and is connected with the wall 41 or' thefair casing. The lower portion of this wall 48 has an inlet opening 52,communicating with the valve chamber 51 and having its walls extended toform a nipple 80, by means of which it may be connected with a stoner orother such device through which it may be desired. to pass a current ofair. The ends of the walls forming the several conduits are preferablycurved to form portions of the Walls of the valve chamber, such wallsconstituting a seat for the valve member (l.

This valve member is of such a character that it can be turned into aposition to connect any one of the three conduits leading to the chamberwith-ithe fan casing and to disconnect the other two conduits therefrom.To this end the valve is of the special construction shown in Fig. 6 andcomprises in addition to its end walls or heads 59 two transverse walls60 and 61 which are spaced apart and curved to form valve ports. T hespace between the partitions 60 and 61 comprises the port 62 and thespace on the outside'of the wall 61 forms the port 63. The relativesize, position and shape of these ports is such that the two ports maybe so Vpositioned thaty any one oi the three conduits will be connectedwith the fan casing. With the valve in the position shown in Fig. 1 theport 63 will connect the conduit 57-23 with the fan casing andtheoperation o,f the fan will draw a current of air through the coffee inthe container 16. B imparting substantially a half revolution to thevalve the wall 60 will be caused to ex- ,tend across the port 55 of theconduit 57 and the wall 61 will extend across the port 52, thus causingthe valve port 62 to connect the conduit 56 with the fan casing. Byrotating the valve a distance sufficient to cause the partition 6l toextend from the partition 63 .to the wall 48 the port 52 will beconnected with lthe fan casing and the other ports cut oli'.
